Indian Study: Abortion Increases Breast Cancer Risk Six-Fold

The Coalition on Abortion/Breast Cancer reports on a study published in the Indian Journal of Community Medicine (May, 2013) whose authors found a 6.38-fold greater risk of breast cancer among women with histories of induced abortion. [1] The study, led by Ramachandra Kamath, MD (Department of Public Health, Manipal University), found induced abortion was the most important risk factor.

“With only 94 cases and 94 controls, the study was way too small for a significant risk of the order of 1.5-fold to even show up,” explained Professor Joel Brind (Baruch College, City University of New York). “Yet induced abortion did show up as the strongest risk factor (and right on the border of statistical significance) because the risk increase was so high at 6.38-fold.”

The authors found a non-statistically significant 1.76-fold risk increase among women with first births after age 30. “Medical texts acknowledge delayed first full term pregnancy is a risk factor for breast cancer,” said Karen Malec, president of the Coalition on Abortion/Breast Cancer. “It’s indisputable that abortion contributes to delayed first full term pregnancies; and in some cases, women remain childless forever, which is also an accepted risk factor.”

Kamath’s group observed that India has the “largest estimated number of breast cancer deaths worldwide,” and breast cancer rates are on the rise there.
